|Binomial name||Pekania pennanti|
The fisher is a small, solitary, mainly nocturnal, aggressive, and elusive weasel. They are related to the American marten.
Their color varies from dark brown to black, with a lifespan of seven years in the wild and, in rare cases, up to 14 years in captivity. They measure from 75 to 120 cm and weigh from 2 to 6 kg.
The fisher is a carnivore that eats mice, snowshoe hares, birds, cats, poultry, shrews, porcupines, and squirrels.
Even though they move on the ground most of the time, they are excellent climbers.
They live in forests in the southern part of Canada and the northern and western part of the United States.
